Highest quality work at a fair price. Jonathan kept me informed every step of the way and there were no surprises at the completion of the job. The workers were great guys - very personable. They worked in less than ideal weather conditions at times, but that didn't appear to slow them down at all. They even tolerated my goofy dogs, which is a plus. For our next construction project, I'm not wasting time with estimates from other companies - my only call will be to JJ's Custom Builders. If you want the absolute best in a contractor, you'll do the same.
